What policy describes the media type used for data archiving?

The retention format specifically addresses the media type or format used for archiving data, dictating how information should be stored over time. This policy is essential since it ensures that the archived data is formatted in a way that is consistent with the organization's needs and compliant with legal and regulatory standards. The retention format can define specific file types, encoding standards, or even types of storage media, which are critical to maintaining the integrity and accessibility of archived information.

In contrast, a data retention policy refers broadly to the timeframe that data should be kept and the eventual deletion of data, without focusing on the specifics of formatting. A data storage policy outlines how and where data is stored but does not necessarily address the requirements for archiving specifically. An access control policy governs who has permission to access certain data, not the media type used for archiving purposes. Thus, "retention format" is the most accurate choice for describing the media type used for data archiving.
